Transmutation Circle (Extruder Rotation Indicator)

thingiverse

I've been impressed by various designs for extruder indicators, but I felt a missing piece was a unique metal twist. Here are three different transmutation circle variants to cater to your desired level of detail. I've uploaded them as 3mf files, which work best for me, although due to Thingiverse rules, I'm required to upload at least one stl file, which is why the "ignore" file exists. The classic 5 cm circle is a standard indicator size, but I found the 7.5 cm variant allows more detail when using a 0.4 mm nozzle. If you prefer a different color backfill, simply change the filament color at either 0.6 mm or 0.8 mm layer height. The magnet circles are designed for 6x3 mm magnets and fit perfectly into the Prusa extruder motor indentation. Have fun printing!
